My invention reiates to stair-treads.

It has for its object to provide a plate adapted to he placed over and engege a piece of carpet on a stair-step andhe secured to said step so as to hold the carpet in place thereon, whereby a soft attractive protecting tread is provid ed for stair-steps.

It has for a further object to provide a stair-tread embodying advantages in point of simplicity and expensivoness of construction,

durability, and generell utility.

In the drawings, Figure l is a bottom pian view of the plate, )artly broken away. Fig. 2 is a longitudinal'vertical sectional View of the plate, showing it in position on a stair step and securing e piece of carpet thereon. Fig. 3 is alongitndinal vertical seriional View of the late.

In all the figures of the drawings iilnstrating my invention like reference characters designate correspond ing parte.

Referring to'the'drawmgs, the stair-tread comprises a plate having a horizontal portion l provided With a dovvnvmrdhVT and inwardiqit` extending front portion l?. A hole 3 is provided in the horizontal and front portions, the edges of the horizontal portion bordering the opening being provided with down- Wardly-extendmg prongs 4, and the edge of the front portion bordering the opening eing provided with laterally-extending prongs 5. A recess 6 in the under side of the plate hordersthe opening therein, and holes 7 in the horizontal portion and 8 in the front portion provide' means for fastening the piate to the step.

o hold a ieee el carpet on a stair by means of my p ate, l press the carpet into the recess 6 so that the pron e pass into it, place the plate on a step and rive it back so that thefront portion engages under the front edge of the step and the prongs 5 pass entirely into the carpet, then force t ie plate down so that the prongs 4 pass entirely into it, end finally secure the plate to the step by means of screws 9, passed through the holes 7 and 8 therein into the steps.

It will be seen from Fig. 1 of the drawings` that vwhen the late is attached in the Inanner described t ie carpet will project through the hole therein beyond its outer surface and will be securely held.
